I think this is as NJ put it, trendy vocabulary too. I usually don't use the term "head games" but I have used the word "drama". Not so much in personal ads though. I've been through some drama in my life - a couple of events that could've landed those of us involved on Jerry Springer! Once in 1989, and then again in 1994-95 with a totally different set of involved people! Or it could be described as something out of a soap opera. I've often said that I don't like soap operas because I've lived one a few too many times! And to get soap opera now, I just have to talk to some of my friends who have some rather, er, interesting events happen in their lives frequently. (Kind of like how "May you live in interesting times" is a curse!)
